Names Used by Psychologists To the psychologist, late childhood when children's major concern is acceptance by their age-mates and membership in a gang. especially a gang with prestige in the eyes of their age-mates. Because of this absorbing concern, children are willing to con-form to group-approved standards in terms of appearance,speech, and behavior. This has led psychologists to label late childhood as this age of conformity. How important conformity to gang-approved standards is to older children has been explained thus by Church and Stone.
